It is well known fact that construction industry is prevailing largely based on OPC. The OPC has its drawbacks as the manufacturing process produces large amounts of greenhouse gases which is impacting the environment adversely. As the advancement of technology increased day by day new alternatives are preferred in making concrete. These alternatives include by-products like fly-ash, GGBS. silica fumes etc. in this present study GGBS is considered for making geopolymer concrete by completely replacing cement and using alkaline liquids for polymerisation process to take place. The mechanical properties of this geopolymer concrete made with 100% GGBS (G.G.C) are studied to understand its behaviour under compression, tension and flexural loads. The geopolymer concrete is made by considering three molar concentrations on NaOH solution used in alkaline liquids. A comparison has been made between these molar concentrations. The compression, tensile and flexural strengths showed a maximum value at 12 molar concentrations when compared with 8M and 10M solutions.
